Abstract

A 2-yr study was conducted to evaluate bell pepper response and honeyvine milkweed control from PRE herbicides, clomazone and trifluralin, applied under polyethylene mulch. Clomazone (0.8 and 1.4 kg ai ha−1) and trifluralin (0.7 and 1.1 kg ai ha−1) were applied alone or in combination. Herbicides were applied after beds were made and before polyethylene mulch was laid, followed by transplanting pepper within hours of herbicide application. In both years, initial bleaching of lower leaves was observed; the injury was observed in some treatments, but not others. Honeyvine milkweed, growing in the planting hole, exhibited significant bleaching and stunting in most herbicide treatments. Both clomazone and trifluralin resulted in season-long honeyvine milkweed control in both years. However, the use of clomazone and trifluralin together for control of honeyvine milkweed does not seem justified due to the potential for herbicide antagonism, as indicated in this study. The total number and fresh weight of harvested bell pepper were not affected by the herbicides or rates. All herbicide treatments resulted in about twice the yield (average of 8.8 kg) of the hand-weeded control (4.6 kg) in both years. This study strongly supports the safety and effectiveness of clomazone and/or trifluralin applied pretransplant under polyethylene mulch in bell pepper production for control of honeyvine milkweed.

Se realizó un estudio de dos años de duración para evaluar la respuesta del pimentón y el control de Cynanchum laeve con los herbicidas PRE clomazone y trifluralin, aplicados bajo cobertura plástica (polyethylene). Clomazone (0.8 y 1.4 kg ai ha−1) y trifluralin (0.7 y 1.1 kg ai ha−1) fueron aplicados solos o en combinación. Los herbicidas se aplicaron después de hacer las camas de siembra y antes de poner la cobertura plástica, y unas horas después se trasplantó el pimentón. En ambos años, inicialmente se observó un blanqueamiento de las hojas inferiores del pimentón, en algunos de los tratamientos, pero no en otros. Las plantas de C. laeve que estaban creciendo en el orificio de siembra, exhibieron significativos niveles de blanqueamiento y retrasos en el crecimiento en la mayoría de tratamientos de herbicidas. Tanto clomazone como trifluralin resultaron en control de C. laeve que duró a lo largo de toda la temporada en ambos años. Sin embargo, el uso conjunto de clomazone y trifluralin para el control de C. laeve parece que no se justifica debido al potencial de antagonismo, como se indicó en este estudio. El número total y el peso fresco de los pimentones cosechados no fue afectado por los herbicidas o las dosis. Todos los tratamientos de herbicidas resultaron en cerca del doble del rendimiento (promedio de 8.8 kg) en comparación con el testigo con deshierba manual (4.6 kg) en ambos años. Este estudio sustenta el uso seguro y efectivo de clomazone y/o trifluralin aplicados pre-trasplante bajo cobertura plástica en la producción de pimentón para el control de C. laeve.
